Golden Eagle M870 - feeding issues

[Rooby512]

So, I have a Golden Eagle M870 gas shotgun that is only feeding every so often.

A little while back a shell got stuck and refused to eject and so, i had to force it out. Ever since then, when loading a full shell and racking, it won't fire anything (other than the gas) but every so often it will pick up rounds in to the chambers and fire as normal.

If remove the shell and manually push a BB in to the feed, I can watch it being racked and it will fire. So im uncertain of the cause of this issue.

Has anyone encountered this before? Or have any advice?

Could be broken nozzle but you have to take it apart regardless.

Have you tested it with any other shells? 

Mine had an issue out of the box with the shell getting stuck and would not eject, I have found being a bit more forceful with the shell door release button it ejects just fine.
